[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Please refer to Figures 1 to 4 As shown, a UBE channel includes a sleeve 100, a tapered tube 110 and a stripper 130. The end of the tapered tube 110 with a smaller outer diameter can extend from one end of the sleeve 100 and is located inside the sleeve 100, and the end of the tapered tube 110 with a larger outer diameter is fixedly connected to one end of the sleeve 100. When the tapered tube 110 is installed in place on the sleeve 100, there is a certain space between the sleeve 100 and the tapered tube 110 to form a guide cavity 111, which is used to temporarily store and guide liquid to pass through.

[0026] A flow guide hole 101 connected to the flow guide cavity 111 is formed on the wall of the sleeve 100, and the flow guide hole 101 is about 1.5 cm away from the end of the sleeve 100 connected to the conical tube 110. The staff can install a joint on the flow guide hole 101 and connect it to an external liquid collection device through a pipeline.

[0027] In addition, when the UBE channel is assembled, the conical tube 110 is sleeved on the stripper 130, and the end with a smaller outer diameter of the conical tube 110 is sealed and connected to the outer wall of the stripper 130 to prevent liquid from entering the conical tube 110. Both ends of the stripper 130 are located outside the sleeve 100, one end of which is used to process soft tissue, and the other end is a handheld end.

[0028] The device can solve the problems of soft tissue cleaning, soft tissue obstruction, difficulty in tool entry and poor water flow at one time.

[0029] When establishing a soft tissue working channel, the staff needs to assemble the UBE channel first, and then insert the end of the cannula 100 that is not connected to the tapered tube 110 into the human body through a surgical incision. The end of the stripper 130 located at this end can separate the soft tissue and divide the soft tissue to both sides of the cannula 100 to prevent the soft tissue from entering the cannula 100 and causing the internal space of the cannula 100 to be reduced, thereby facilitating the establishment of the soft tissue working channel and ensuring that the surgical tools can smoothly pass through the tapered tube 110 into the body. After the UBE channel is inserted to the desired position, the staff can remove the stripper 130 from the cannula 100. At this time, the liquid in the body can enter the diversion cavity 111 through the end of the cannula 100, and enter the collection device through the diversion hole 101.

[0030] Specifically, the cannula 100 is a cylindrical structure with a smooth surface, and the outer corner formed by the end surface of the cannula 100 that is not connected to the tapered tube 110 and the peripheral wall of the cannula 100 is rounded to reduce friction with human tissue and facilitate the cannula 100 to enter the human body. The cannula 100 is about 15 cm long, with an inner diameter of about 1 cm and an outer diameter of about 1.2 cm.

[0031] Please refer to Figure 3 The conical tube 110 includes a tube portion 113 and a connecting portion 115, the connecting portion 115 is fixedly connected to one end of the tube portion 113, and the connecting portion 115 is connected to the sleeve 100. In this embodiment, the connecting portion 115 and the sleeve 100 are detachably connected to facilitate intraoperative operation. The connecting portion 115 includes a T-shaped connecting seat 117 and a first sealing member 119. The first sealing member 119 is a sealing ring, and the first sealing member 119 is sleeved on the T-shaped connecting seat 117. A portion of the T-shaped connecting seat 117 extends into the sleeve 100 and is threadedly connected to the inner hole wall of the sleeve 100. The first sealing member 119 can seal the connection between the connecting portion 115 and the sleeve 100 to prevent the liquid from entering the diversion cavity 111 and flowing out from the end of the sleeve 100.

[0032] Preferably, a second sealing member 118 is provided at one end of the tube portion 113 away from the connecting portion 115. The second sealing member 118 is provided with an escape hole for the stripper 130 to pass through. In this embodiment, the second sealing member 118 is a sealing ring, and the second sealing member 118 is sealedly connected to the peripheral wall of the stripper 130. When the stripper 130 or a surgical tool passes through the escape hole, the second sealing member 118 needs to be squeezed to prevent liquid from entering the tapered tube 110.

[0033] Preferably, the inner hole of the conical tube 110 is a cylindrical hole (not shown in the figure), and the outer wall of the stripper 130 is gap-connected with the inner hole of the conical tube 110, thereby preventing the stripper 130 from shaking when the UBE channel enters the human body and causing excessive damage to human tissue.

[0034] Please refer to Figure 4 The stripper 130 is about 20 cm long and includes a rod 131 and a handle 133. The handle 133 is a ","-shaped plate-like structure that fits the natural shape of the human body, so that the person using the stripper 130 does not need to actively adapt physically and mentally when working, thereby minimizing fatigue caused by using the stripper 130. One end of the rod 131 is fixedly connected to the handle 133, and the end of the rod 131 away from the handle 133 is a flat structure, and the length of the flat part is about 2 cm, which is conducive to the end processing soft tissue.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
